  Comprehensive Experimental Study of N-Heterocyclic π-Stacking Interactions of Neutral and Cationic Pyridines

  摘要：

  A comprehensive experimental study was carried out by measuring the relative strengths of parallel pi-stacking interactions of N-heterocycles with nonheterocycles. A versatile and rigid model system was developed, which was in equilibrium between a "closed" conformation that forms an intramolecular pi-stacking interaction and an "open" conformation that cannot form the interaction. First, the formation and geometries of the intramolecular N-heterocyclic pi-stacking interactions were verified by X-ray crystallography. Next, the closed/open ratios were measured in solution via integration of the H-1 NMR spectra, providing an accurate comparison of the N-heterocyclic pi-stacking interactions. The synthetic versatility of this model system enabled the systematic and comprehensive comparison of the influences of position, charge, and substituent effects of the nitrogen atom of the N-heterocycles within a single model system. The pi-stacking interactions of the neutral N-heterocyclic rings were slightly stronger than that of nonheterocyclic rings. Cationic N-heterocycles formed significantly stronger pi-stacking interactions than neutral N-heterocycles. The position of the nitrogen atom also had a strong influence on the stability of N-heterocyclic pi-stacking complexes. Interestingly, opposite stability trends were observed for neutral and cationic N-heterocycles. For neural N-heterocycles, geometries with the nitrogen away from the pi-face of the opposing ring were the more stable. For cationic N-heterocycles, geometries with the nitrogen close to the pi-face of the opposing ring were the more stable. Finally, N-methylated heterocycles consistently formed stronger pi-stacking interactions than N-protonated heterocycles.

  comprehensive experimental survey consisting of 36 molecular balances was conducted to compare 18 pairs of S-π versus O-π interactions over a wide range of structural, geometric, and solvent parameters. A strong linear correlation was observed between the folding energies of the sulfur and oxygen balances across the entire library of balance pairs. The more stable interaction systematically switched

  进行了由 36 个分子平衡组成的综合实验调查，以在广泛的结构、几何和溶剂参数范围内比较 18 对 S-π 与 O-π 相互作用。在整个平衡对库中硫和氧平衡的折叠能之间观察到很强的线性相关性。更稳定的相互作用系统地从 O-π 转换为 S-π 相互作用。双分子PhSCH3-芳烃和PhOCH3-芳烃复合物的计算研究能够复制分子平衡的实验趋势。O-π 到 S-π 相互作用的偏好变化是由于稳定（分散和疏溶剂）和不稳定（交换排斥）术语的相互作用，这是由于氧和硫原子的大小和极化率的差异引起的。

  The invention is based on the discovery that adhesive compositions containing certain low-viscosity, mono-ethylenically unsaturated monomers have surprisingly good cure parameters, resulting in very little weight loss upon cure. Many of these monofunctional monomers used alone or in combination with other monofunctional monomers described herein have high glass transition temperatures when cured. Moreover, since these monomers are monofunctional the crosslink density of the adhesive composition does not increase (relative to multi-functional monomers), which in turns results in lower stress, lower modulus adhesive compositions. As such, these monomers are useful in a variety of thermoset adhesive compositions, such as for example, die attach adhesive compositions.

  该发明是基于发现，含有某些低黏度、单乙烯不饱和单体的粘合剂组合物具有惊人的固化参数，固化后重量损失非常小。其中许多单官能单体单独使用或与本文所述其他单官能单体组合使用时，在固化后具有较高的玻璃转移温度。此外，由于这些单体是单官能的，粘合剂组合物的交联密度不会增加（相对于多官能单体），这反过来将导致较低的应力、较低的模量粘合剂组合物。因此，这些单体在各种热固性粘合剂组合物中非常有用，例如，封装粘合剂组合物。
